Description
Julian Allwood and Omer Music ask how much of the world's steel and aluminium is truly needed, in a 2024 article. Making these metals drives a large share of industrial emissions, and clean supply will fall short of demand for decades. The pair estimate waste at the level of parts and components rather than whole industries.
Their answer is stark: about eighty percent of liquid steel and ninety percent of liquid aluminium made today may be unnecessary. Much metal is cut away during making and never reaches a finished part. Of what does, about a third could be saved by not over-building parts, and another third by using the metal's strength more fully. The authors point first to rethinking sheet metal in construction.
